Some probem in starting up kernel from U-Boot

Hi Scott:

Thanks you!When this flash utilities is completed, it's very convenience to download kernel and filesystem to flash.

But now, i use the flash-program in NIOSII IDE to complete the flash function.Also it works good.

So how to fix this kernel panic below, i try to fix it ,but no result.Hopefully you have a good idea:-)

Thank you!
